Application filed November e1, 1921. Serial Nb. 515,700.

To all whom it may concern:

Be it known that I, HERBERT AnRAi AM, a citizen of the UnitedStates, residing in the city, county, and State of New York, have in overlapping courses.

The present types of self-spacing shingles provided with guides indicating exposme are so designed that they cannot be manufactured without loss or waste of material. This of course, increases the cost of the shingles.

My invention aims to provide self-spacing shingleswith guides indicating the proper exposure to the weather which are designed to be cut from a web or sheet of prepared roofing material without waste; and which have other advantages hereinafter set forth.

In the accompanying drawings illustratingra preferred embodiment of the invention.

igure 1 represents a portion of a web or sheet of roofing material, with the lines for cutting the shingles indicated thereon.

Figure 2 shows two of the shingles as cut but slightly separated. j

Figure 3 is a similar viewshowing the shingles positioned for use, and,

Figure at is a plan view of a section of roof laid with such shingles.

Referring to Figure 1 of the drawingsit will be-seen that the web or sheet is cut into series of complementarypairs of units or shingles A and B, two of which are shown slightly separated in Fig. 2. Before laying, each alternate unit B is turned up-- side downin its own plane as indicated in Figure 3 so that the edges of the adjacent units A and B which were contiguous when out, will be remote when laid.

In cutting, each unit A is provided at the upper portion of one side with a projection 1 which is the complement of the recess 2 of the contiguous unit B, and which is substantially equal in width to the horizontal dlstance or slot 12 between the lower portions or butts of adjacent units when laid as shown in Figure 4c- Directly below the middle of each unit A.

and on the same side as the projection 1 is" a second projection 3. .The act of cutting the projection 3 forms a projection 41: on'

the contiguous edge of theunit B and also forms a recess 5 inthe' lower portion of the unit A, which recess has its complement in the projection 6 of the unit B.

\Vhile I prefer to have the projection 3- rectangular in configuration, it may be of other shapes. It is essential however, that the lower corner 7 of the projection be spaced vertically from the lower edge of the unit a distance substantially equal to the vertical extent that the unit is intended to be exposed when laid as shown in F ig. 4, and that said corner be spaced horizontally from the body of the unit a distance substantially equal to twice the width of the space or slot 12 between the" lower portions of ad- 'jacent units when laid.

On the lower portion of each unit A and extending above the middle thereof, on the side opposite to that having the projections 1 and 3, is another projection 8. The pro jection 8 is similar in width to the projection 1 but islonger, extending upwards to a point opposite to the lower edge of the projection 1. The manner of cutting the projection 8 of the unit A, of course, forms a complementary recess 9 in the contiguous unit B, and also forms a projection 10 on the upper part of said unit B, which projection is similar in'dimensions to the projection 1 of unit A. It will be seen that the projection 10 is the complement of recess 11 of unitA.

The manner of cutting hereinabove described produces self-spacing shingles which can be formed without loss or waste of any material except that which must be trimmed from the ends of the sheet in the cutting operation. Furthermore, such shingles can be conveniently stacked, and packed in substantially rectangular 'shap'ed p'ackages for shipment, by laying-one on the other.

The units'B are turned" upside down in their own plane, as hereinabove mentioned and as shown in Fig. 3;:to bring them into; laying position. In laying a roof, the shingles are laid side by side in a row to form a course in which the units A and B alter nate, and with similar courses successivelyapplied thereon in overlapping relation as shown in Fig. 4; thisbeing the usual method of laying such roofs. The units are fastened to the roof deck by nails 13, which are preferably positioned as indicated in ig. Itiwill" be observed that when the shlngles are laid and fastened as shown, each unit' is held down by two nails, one of which is driven directly into the unit, and the other of which penetrates through from theunit above. Furthermore, it-will be seen that the nail heads of the shingles of each lower course are covered by the shingles otteach upper course.

When la'id'as described, the projection e,

of each unit B fits into the recess 11 of the laterally adjacent unitA, and the projection against the lateral edge of unit B directly above the shoulder between the projection 10 and recess 9 of the latter.. It will be noted. I that a space or pocket is formed in the points between units B-A and A-B above the projections 3 and 4, respectively; Should the Wind drive any 'water'up beyond the top of the slot 12, the interposition of said space will prevent the water from traveling further along the joint. I

What I claim is:

1'. A pair of self-spacing prepared roofing elements adapted to be laid-with other SlIIlilar pairs in overlapping courses in simulation of ashingledroof, comprising elements each having two spaced projections of different widths on onelateral edge, and a single projection, corresponding in w dth to the narrower of the first mentioned projections, on the opposite lateral edge.

2. A pair of self-spacing prepared roofing elements adapted to be laid with other similar pairs in overlapping courses in simulation of a shingled roof, comprising elements each having two spaced projections on one lateral edge, one of said projections being double the width of the other, and a single projection corresponding in width to the narrower of the first mentioned projections on the oppositelateral edge.

3. A pair of self-spacing prepared roofin elements adapted to be laid with other similar pairsin overlapping courses in simuladown, in simulation of ments of the projections maagava tion of a'shingled roof, comprising elements each having two spaced projections on one lateral edge, the width of the base, of one ing in width to the narrower of the first-mentioned projections and forming a-sh'oulder seat forthe wider projection of the next laterally adjacent element when laid.

l. A pair of self-spacing preparedroo'fing elementsadapted to be laid with other similar pairs in overlapping courses in simulation ofa shingled roof, comprising elements paced pro ections on one each having tWo s lateral edge,thew1dth of the base ofone of said projections being equal to the width of the space between the exposed portions 'of the laterally adjacent elements when laid, the base of the'other of said projections being double said width, the distance measured vertically from the lower edge of the element to the base of the lower of saidprojections being equal to the vertical extent" that the element is intendedto be exposed when laid, and a single projection on the other lateral edge corresponding in width to the narrower of the first mentioned projections and forming a shoulder-seat for the wider projection of the next laterally adjacent element when laid.

5; Self-spacing prepared roofing elementpairs-adapted to be out without wasteand to be laid in overlapping courses, with alternate elements of each course turned upside a shingled roof, each element having two parallel straight sides and two sides provided with projections, the projections on either side being the comple of the adjoining element in cutting position and forming abutments for spacing adjacent elements in laying position.

6. Self-spacing prepared roofing elementpairs adapted to be out without waste and to be laid in overlapping courses, with alter'; nate elements of each down, in simulation of a shingled roof, each, element having two parallel straight'sides and two sides provided with projections, one of the latter having a single projection and the other a plurality of projections,- the projections-on either side being the com plements of the projections of the adjoining element-in cutting position and forming abutments for spacing adjacent elements in laying position.

7. Self-spacing prepared roofing element pairs adapted to be cut without waste and to course turned upside? be laid in overlapping courses, .with alter element having two parallel straight sides and two sides provided with projections, one of the latter sides havinga single projection of a width substantially equal to the Width of the space between the exposed portions of adjacent elements When laid, and'the other having a plurality of projections one of which is double the Width of the projection v on the opposite side, the projections on either side being the complements of the projections of the adjoining element in cutting position and forming abutments for spacing adja cent elements in laing position.
